Achievements of Guangdong Institute of Geological Surveying and Mapping

Our institute has successively completed the third-and fourth-class plane control and second-and third-class leveling in some areas of Guangdong Province, the mapping and compilation of 1: 1 000 topographic map, and the basic mapping of Guangdong Province 1: 50,000 to1500,000 geological map, and participated in the national defense projects and nuclear power plants in Guangdong Province. The investigation of the Pearl River Basin water control project and the large-scale mine exploration projects such as Yunfu pyrite mine, Shaoguan Fankou lead-zinc mine, Dabaoshan iron mine and Zhaoqing Hetai super-large gold mine have made due contributions to Guangdong's economic and social development. Participated in the investigation of key construction projects such as Guangzhou New Baiyun International Airport, Chaoshan Airport, Guangzhou-Shenzhen-Zhuhai Expressway, Beijing-Guangzhou Expressway, Guangzhou-Zhuhai Rail Transit, Guangzhou Metro, Humen Bridge, Guangdong Olympic Sports Center, Guangzhou Asian Games and New Guangzhou TV Sightseeing Tower. Guangdong-Hainan Geological and Mineral Map, South China Sea Wan 'an Basin Structural Map, Guangdong Mineral Research Degree Map, Metallogenic Law Map and Prospective Planning Map, Shantou Geological and Mineral Structure Outline Map, Yunfu, Sanshui, Nanhai, Taishan and Heshan Administrative Division Map, Guangzhou Highway Map, Zhanjiang and Maoming were compiled and printed. In recent years, our institute has actively responded to the national policy, relying on strong technical force and excellent service, and completed the land renewal survey project in Guangdong Province 14 counties (cities, districts) and the second national land survey project in more than 20 counties (cities, districts). Topographic cadastral surveys and land use change surveys at various scales have been completed in more than 50 counties (cities, districts) including Guangzhou, Foshan, Shenzhen, Zhuhai, Shantou, Jiangmen, Zhanjiang, Meizhou, Zhaoqing, Yangjiang and Yunfu. 20 12 undertook the registration and certification of rural collective land ownership in 20 counties (cities, districts) of Guangdong Province. Gaoming and Huaiji passed the national spot check and acceptance, and achieved excellent results. Completed aerial photography and 4D data production in Gaoming District, luoding city, Huaiji County and Fengkai County, and independently developed rural collective land ownership registration and certification system, land subsidence geological disaster monitoring information management system in Pearl River Delta, office automation management information system of Provincial Geological Bureau, homestead certification information system of Huadu District Land and Resources Bureau and "wide map" application system. It has undertaken projects such as land development, land consolidation, land evaluation, revision of land use master plan, high-standard basic farmland, urban master plan and the increase or decrease of urban and rural construction land in Yangchun, Yangxi, Yangdong, Gaoming, Luoding, Xinyi, Nanxiong, Dapu and Jieyang.

In recent years, our institute has also completed the field verification of mining rights in Guangdong Province, the monitoring of land subsidence geological disasters in the Pearl River Delta and its surrounding areas, the application research of land subsidence monitoring system with high temporal and spatial resolution in disaster prevention and mitigation, and the compilation of 1:25000 geographical base map of Nanling metallogenic belt and Wuyi metallogenic belt in Guangdong Province, and obtained excellent grades in performance evaluation.

Our institute takes "production, learning, research and innovation" as the development means, and a number of surveying and mapping achievements have successively won national, provincial and departmental (bureau) excellent engineering awards. Among them, the "Research and Application of InSAR High-precision Surface Deformation Measurement" undertaken by our institute won the first prize of National Surveying and Mapping Science and Technology Progress Award 20 13, and the basic geographic database project built by our institute for Nanhai Branch of Foshan Land and Resources Bureau won "2006". Huizhou Huicheng Urban Land Survey Project and Xinyi Rural Collective Land Confirmation Registration and Certification Project won the first prize of Guangdong Excellent Surveying and Mapping Geographic Information Engineering Award, and several projects won the second and third prizes of the Provincial Geological Bureau.
